摘要： PURPOSE: An adhesive composition that is made by adding a softening agent and a specific terpolymer to a graft polymer prepared by grafting a reactive monomer containing glycidyl groups and an alkyl acrylate onto a vinyl chloride-vinyl acetate copolymer, thus effecting good adhesion between copper tapes and polyvinyl chloride.
CONSTITUTION: First, a glycidyl ester of α,β-unsaturated carboxylic acid and alkyl acrylate, e.g., glycidyl methacrylate and n-butyl acrylate are grafted onto a copolymer of vinyl chloride and vinyl acetate. The resultant graft copolymer is combined with a softening agent and a terpolymer of vinyl chloride-vinyl acetate-maleic anhydride. The resultant resin composition is laid between surfaces of steel or copper to produce laminatings, or a laminated tape made by laminating the composition on one or both surface of a copper tape is used as an insulation layer around a cable core and a polyvinyl chloride sheath is applied thereon to give a laminate sheath type power cable.
